Number 3: Arenal Volcano

The central region of Cappadocia (often misspelled as Cappedocia or Capedocia) in Turkey contains a strange landscape of eroded mountains, featuring caves and canyons in all kinds of colors. Great for hiking.

Number 5: Amboseli National Park, Kenya

Going on an African Safari with the Kilimanjaro in the background. It's almost a guarantee for excellent pictures.
